To all whom t may concern: 4

Be it known'that I, CARL Pn'rnizsniv, a sub. ject. of the King4 of Denmark, residing at San rancisco, in the county yof San Francisco andSta-te of California, have invented certain new and useful Im rovements in Automobile-Locks,of which` t e' following is a s eciiication.

his invention relatesltoaultomobile locks' and the primary object is to provide an attachment whereby the theft of theautomo- .standards 3 fastened to the front end of the yside bar of the frame and the brace bar' 4 fixed in an preferred marmer to the side" bile either under its own in will be prevented. Y

ne of the ob'ects of the iIntentionis to provide an attac ment for the "iront of the automobile which will include wheel en g'- ng members associated with aspecial orm ofA lock adapted to hold the wheel engaging members in a fixed position-so that turning or uiding of the Wheels will be revented.

he invention also aims att e provision :of an improved attac ent for an automo- `-bile which maybe read y placed into opera- *tive position b a simple turn of a con veniently loateband wheel butfwhich will require thefuse""ofV la special key to unlock power or by Atowthe structur when the owner oroperato'r is,

about to use the automobile. 4 i

A further object of the inventio.L is to pro-y vide a device of this character which con sists of comparatively few parts fand is simple in construction, but durable and well sol fadapted to withstand the rough usage to,

which devices of this characterare ordina rilg` subjected.`

is to be had'tqthe following description and Fig. 2 is an enlarged fragmentary section taken on the line 2 2 of Fig. 1. 4l5"\` Fig. 3 is an enlarged. transverse sectlon'.

Fig. 4 is a section taken on the line 4 4 of Fig. 1. 'l

Fig. 5 is an enlarged plan view of the locking mechanism.

Fig. 6 is a longitudinal section through the same. 4

Fig. 7 is a fragmentary 4longitudinal section taken on a different plane from that shown in Fig. 6.

Fig. 8 is an elevation of the hand Wheel used with the attachment.

or a full description ofthe invention and the advantages .and merits'thereof, reference 'either' direction will. be prevented when the locking levers are'in this osition. Between Referring to the drawin the bumper 1 is mounted at the front en of the-automobile in the usual manner and consists of a length of channel iron having its ends :curved rearwardly and terminating directly in front of the front wheels of the automobile as show n in Fig. 1. The bumper is preferably attached to the front ends ofthe side bars of the automobile frame and to accmlish this, each side bar is provided with aV 'racket 2 which consists of the upright connection' between theyoke Sand-the angle -irons 6 is established Aby tlievvertical bolts 9. I

These bolts9greceive the Aends 'o f the arcuate .brace memberlOthe endsofthe same being provided with'suitable' loops v*11 to receive f thebolts9..`

To thus join the rack bars 14 and 15'with the locklng arm 13 the latter are provided with arcuate slots in which are received t e pins 17 carried by the ends of the rack ba `To actuate the rapk bars for swinging t clocking arms out ofA ngagement ywith the automobile tires, a gear 8 is provided the teeth of which engage the teeth in both rack bars at diametrically opposite points so that the rack' bars will move in opl )site directions when los" the gear is turned. The gear 18 is mounted on n shaft 19 having one end journaled in ih@- vertical wall of the channel iron a'nd its roar end journaled in a bracket Carried by the angle iron (3. The. Center of the arcuate hraec nteinhcr l0 is provided with an opening?r through which the. shaft ttl is extended and thc shaft carries a hand wheel 2O which` may be rotated for imparting the. necessary movenient to the shaft for turninler the'gear 18 whereby the rack bats 14 and l be properly actuated.

"la 4,- 5.- e nd -fr of the drawing; is'

shown a special forni off lock designed for use with this attachment. This lock is mounted between the tlanges of the ehrnnel -iron 1 at u point embraced h r one of the yokes 5. Four fastening bolts :3l are pro- "ided, the heads of which are. conntcrsnuk in the front end of the yoke The opposite ends of the bolts arc 'projected through snitable openings in a retainimr plate which engages thc edges of the e nnmcl iron l as Shownto advantage. in [fi 4. 'I he nuts 23 are mounted upon the en s of the. bolts 21 4 'and engage the late 22 to hold it in applied gsition. The olts 2l carry. rigidly xed tti-bythe enda qfthc plates 29 arcfprovidcd l at apringa are engaged h v Ila-. eiosr: pins 33 10 'also carried by the plato 2%) and tend to 'urgethe springs into position for excrtin u pres- .tiue ou thc latch plate. 26 whereby ie teeth .normally engage thtrteth in tho rack bur .',;15. The latch plates 26 are. of dieront -5 tlaitknesses amlronsequently the sprin 31 "'showi'to advantage in Fi". 5 of the raw- ,.ng, are also -of ditlerent thicknesses. The key 34 employed for operating the latch c, platc consists of the. shank havinga plumlity of disks 3G projecting' therefrom,

encll of which is equal in width to the thiol(- ncsa of tlal eorres|rondiner lati-h plate 26. The. meeting! fnees of the'frnnt ends of the yoke 5 and thc vertirai wall of the ehnnm-l iron 1 are oppositel ieri-#Hed a: indicated at 3T and 35S. Thus :t receiQ provided tn reet-irttlnrotatable disk 39 llif'h ha a lier opt-ning and a slot 4t).

The disk :tti engages one edge of the opening when the keris turned so that the. fpiatsar'e rai-l.ilt.\.l Ll` of engae'ement with thc teeth of thc rack hundir-anc af'ainst the pressure exerted h y the flat sprin3i-.1`lc 80 teeth 2 and 2S however, are constructed so thattlle rar-k har 1.3 may more in one direction but. cannot more in the opposite direction until the key is employed to actuate the lateh plate.

In use, when the o erator desires to leave the automobile-Mandi vin a public place; the loekixn,r levers 13 wi l be swung into engagement with thc`tires'of-th ront' wheel as shown in full lines in Fig. VI. 0 itlle 'drawing.
